If we take 2340 away from 3000, we end up with 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

Advancing to step 13:
780 goes into 6600 8 times with a remainder of 360.
Record the quotient 8 as the next digit in the result. 
Result so far: 102646.91538
If we take 6240 away from 6600, we end up with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Going ahead to step 14:
3600 divided by 780 is 4 with a remainder of 480.
The number 4 becomes the next digit in our result. 
Result so far: 102646.915384
Subtract 3120 from 3600 to get 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.
